====== Fax Line with US Robotics Modem ======

  Phone Line ===> US Robotics ===> Brother Fax
  Configure Brother Fax  - No to easy receive - answer on ring 4
  Configure US Robotics Software - in my case MS Fax on Server 2003 to answer on ring 1
  
==== What is the Easy Receive setting? ====

    OFF means you will have to activate the Brother machine yourself by lifting the handset of an extension telephone on the same line 
    as your Brother machine, then doing one of the following:
        If you are at the Brother machine, press the Mono Start or Colour Start key.
        If you are not at the Brother machine, press *51

====== Telephone Line Parity ======

From: http://www.westernet.net/Help/RJ45.htm

    * Pair 1 
      * White with Blue
        * Tip
      * Blue
        * Ring

From: http://en.wikipedia.org/wiki/Tip_and_ring

    Tip has a potential of 0 volts with respect to ground, while the battery side carries a DC potential of −48V
    when in the on-hook (idle) state (nominally −50 volts in the UK).

From: http://wiki.answers.com/Q/What_is_Phone_line_polarity

    The red wire is the "ring" or negative wire. The green wire is the "tip" or positive wire.
    
From: http://en.wikipedia.org/wiki/Tip_and_ring#Polarity

    tip wire coded green and ring coded red.

From: http://www.eeweb.com/blog/extreme_circuits/phone-line-polarity-checker
    
    Because modern phones rectify the DC voltage from the telephone lines before regulating it and 
    because the ring and voice signals are AC, for voice communications the polarity doesn’t really matter.
